Deket a. (1,2,3) b. (-1,3,5) c. (2,-2,2). Tentukan vektor AB, BC, dan CA

Vektor AB = vektor B – vektor A
= (-1,3,5) – (1,2,3)
= (-2,1,2)
Vektor BC = vektor C-vektorB
= (2,-2,2) – ( -1,3,5)
= (3,-5,-3)
Vektor CA = vektor A – Vektor C
= (2,-2,2) – (1,2,3)
= (1,-4,-1)

intinya di balik lalu di kurangkan
